It is expected to develop into a tropical cyclone tonight (5 September) to tomorrow morning (6 September). The Observatory will consider issuing the Standby Signal, No. 1 by then. Under the influence of an anticyclone aloft, it will still be mainly fine in Hong Kong tomorrow. The weather will be extremely hot during the day, with temperatures reaching about 35 degrees in the urban areas, and a couple of degrees higher in the New Territories. According to the present forecast, the tropical cyclone will intensify progressively and move in the general direction of the coast of Guangdong in the next couple of days, but there are uncertainties in its intensity and speed of movement. Under its influence, winds are expected to strengthen gradually in Hong Kong on Sunday (7 September), and the weather will become unsettled. The weather will be windy with heavy squally showers and thunderstorms on Monday (8 September), and seas will be rough with swells. Due to storm surge, there may be flooding in low-lying coastal areas on Monday morning. Depending on the intensity of the tropical cyclone, the distance of its strong winds from the territory and the changes in local winds, the Observatory will assess the need of issuing higher Tropical Cyclone Warning Signals on Sunday. Members of the public should pay attention to the latest weather information from the Observatory.
